XMen First Class Review!!

Today my little ones were at camp so I took my 13 yr old to see this movie.  Although it was a good movie I was really annoyed!!!  They used GD twice and the F word.  My son leans over and says don't worry mom I hear that all the time at school.  Well, that's not really the point is it??  If it's rated okay for 13 and up then why do our teenagers need to be encouraged to use such language.  If you were planning to take your younger children to see this you might want to see it first!!
